Have you tried the topeak road morph? They're like $30 online and they're as good as floor pumps.

I have saved more than my fair share of people who
a) Did not get their CO2 to fill the tire correctly
b) Did not have an extra CO2 cartridge
c) Did not have a Pump or CO2
d) Did not have an adapter for Schrader.
I Marshall my fair share of Charity rides and by the days end my hands
are sore. Not because of the pump, its the best. Its that too many people count
on the CO2 for more than they think.
Trust me, I have my CO2 in the closet.
Mini-Pumps "may" get you rolling, but never at the proper pressure unless you are an NFL linebacker.
Oh Yeah the Topeak Road Morph comes in 2 models. Don't be cheap, get the one with the pressure gauge, costs $5-$7.50 more.
Good luck
Live an learn then start all over again
